PRIORITY APPLICATION

This Application claims priority under 35 U.S.C. Section 119(e) to U.S. Provisional Application 62/097,478, filed Dec. 29, 2014, and titled “Low-power Wireless Content Communication between Devices,” the entire disclosure of which is hereby incorporated by reference.

BACKGROUND

The popularity of wearable devices has continued to increase as the amount of functionality made available via these devices has increased. Additionally, this popularity has also followed increases in the portability of the devices. However, these factors often conflict with each other.

For example, an increase in bandwidth supported by the wearable device to transfer data has a corresponding increase in an amount of power consumed by the wearable device, thereby limiting portability of the device due to frequent recharging of the device. Consequently, functionality available via the wearable device is often limited by these factors, which also limits desirability of consumers in purchasing the device due to the tradeoffs required in portability and functionality under conventional techniques.

DETAILED DESCRIPTION

Overview

Wearable devices are typically limited by the desired portability of the device, even more so than other portable computing devices such as mobile phones and tablets. Accordingly, wearable devices may be limited by an amount of power available from a battery as well as by devices that consume this power, such as processing systems, memory, display devices, wireless communication devices, and so forth. For example, conventional low power wireless communication techniques do not support transmission of large items of content, such as audio or video to conserve battery resources.

Low-power wireless content communication techniques are described. In one or more implementations, content such as audio or video is communicated to a wearable device over a low-power connection that does not have sufficient bandwidth to support real-time output by the wearable device. Examples of low-power wireless content communication include Bluetooth® Low Energy, Wi-Fi Low Energy, 2.4 GHz wireless protocols, and so on. In order to accomplish this, transfer of portions of the content is managed to send the portions when the wireless connection is available, e.g., in range of a computing device having one or more of the portions.

Management may also include use of different computing devices, such as devices associated with a user's account as part of a network service such that different devices send different portions of the content when available. This management is performable by the wearable device, the computing devices, and/or a service backend. In this way, small, low power wearable devices are provided with content that otherwise is not available to the devices over a wireless connection, thereby promoting portability of the device. Further discussion of these and other examples are described in the following sections and shown in corresponding figures.

In the following discussion, an example environment is first described that may employ the low-power wireless content communication techniques described herein. Example procedures are then described which may be performed in the example environment as well as other environments. Consequently, performance of the example procedures is not limited to the example environment and the example environment is not limited to performance of the example procedures.

Example Environment

FIG. 1 is an illustration of an environment 100 in an example implementation that is operable to employ low-power wireless content communication techniques described herein. The illustrated environment 100 includes a computing device 102, a wearable device 104, and a service backend 106. Computing devices that implement these entities are configurable in a variety of ways.

The computing device 102, for instance, may be configured as a desktop computer, a laptop computer, a mobile device (e.g., assuming a handheld configuration such as a tablet or mobile phone as illustrated), and so forth. Thus, the computing device 102 ranges from full resource devices with substantial memory and processor resources (e.g., personal computers, game consoles) to a low-resource device with limited memory and/or processing resources (e.g., mobile devices). Likewise, computing devices that implement the service backend 106 are also configurable in a variety of ways, such as multiple servers of one or more server farms as illustrated. Additionally, although single computing device examples are shown, a computing device may be representative of a plurality of different devices as further described in relation to FIG. 6.

The wearable device 104 has a housing that is configured to be worn by a user. As such, the housing of the wearable device 104 may take a variety of different forms, such as a ring, broach, pendant, configured to be worn on a wrist of a user as illustrated, glasses as also illustrated, and so forth. The wearable device 104 includes a battery 108 and a low-power wireless communication device 110 that are disposed within the housing.

The low-power wireless communication device 110 is configured to support wireless communication that consumes a low amount of power of the battery 108. As such, however, protocols used by the low-power wireless communication device 110 have limited bandwidth. As a result, these protocols do not support streaming of the content in an amount that is sufficient to support real time playback of the content at the wearable device, e.g., of audio or video by output devices such as speakers or a display device of the wearable device 104.

Accordingly, the computing device 102, the wearable device 104, and service backend 106 are illustrated as including respective transfer manager modules 112, 114, 116. The transfer manager modules 112, 114, 116 are representative of functionality to manage transfer of content 118 (e.g., audio or video) to the wearable device 104 for local storage on the wearable device 104. In this way, the wearable device 104 may still conserve power of the battery 108 yet have access to expanded functionality through playback of the content 118 that was not otherwise accessible wirelessly by the wearable device 104.

This management is performable singly or in combination by one or more of the transfer manager modules 112, 114, 116. Transfer manager module 114 of the wearable device 104, for instance, may ping the computing device 102 over a wireless connection formed between the low power wireless communication device 110 and a wireless communication device 120 of the computing device 102 to obtain the content 118. In this way, the transfer manager module 114 of the wearable device 104 controls the transfer of the content 118 in this instance.

In another instance, the transfer manager module 112 controls the transfer of the content 118 to the wearable device 104, such as to send portions of the content 118 when the wearable device 104 is in range of the lower power wireless connection. This may be performed to control transfer of the content 116 using a single computing device 102 as shown in FIG. 2 and may even employ a plurality of computing devices as shown in FIG. 3.

The transfer manager module 116 of a service backend 106 may also be employed to control the transfer of content 118. The service backend 106, for instance, includes one or more services that are accessible to a user of the computing device 102 via a network 122. The services include storage 124 of content 118 that is provided to the computing device 102 via the network 102, roaming of user settings associated with a user's account, social network services, and so on. Accordingly, login to the services may be performed to access content 118 that is to be consumed by the computing device 102 and/or the wearable device 104 via a user's account. Further, the transfer manager module 116 of the service backend 106 is configurable to control how the content 118 is transferred to the wearable device 104, such as to select which computing device 102 to employ and so forth, an example of which is shown and described in relation to FIG. 4.

In the illustrated example, due to limitations of the low power wireless communication device 110 the service backend 106 is not directly accessible to the wearable device 104, but is directly accessible to the computing device 102, e.g., via the Internet. As such, content 118 is communicated from the service backend 106 to the computing device 102 via the network 122, and then over a low power wireless connection illustrated through use of an arrow between the computing device 102 and the wearable device 104 in this example. Other examples are also contemplated without departing from the spirit and scope thereof. Further discussion of low-power wireless content communication techniques is described in the following and shown in corresponding figures.

FIG. 2 depicts a system 200 in an example implementation in which control of transfer of content over a low power wireless connection is managed responsive to availability of the connection. The system includes the computing device 102 and the wearable device 104 of FIG. 1. In this example, the content 118 is divided into a plurality of portions, examples of which are illustrated as a first content portion 202 to an N content portion 204. These portions are transferred in this example responsive to a detection of availability of the low power wireless communication connection between the computing device 102 and the wearable device 104.

For example, the computing device 102 is illustrated as included at a center of four concentric circles that illustrate a wireless range supported by the low power wireless communication connection. Accordingly, when the wearable device 104 is disposed at a location 206 that is within this range, the first content portion 202 of the content 118 is transferred to the wearable device 104 as illustrated by the arrow in the figure.

However, this transfer ceases when the wearable device 104 is disposed at a location 208 that is outside this range, and then resumes when the wearable device 104 is disposed at a location 210 back within the range of the connection as also illustrated by inclusion of an arrow or lack thereof in the figure. In this way, the different portions of the content 118 (e.g., first content portion 202 through N content portion 204) are provided automatically and without user intervention based on availability of the connection.

This transfer, as previously described, is manageable in a variety of ways. The transfer manager module 114 of the wearable device 104, for instance, may form requests for portions of the content 118, e.g., may “ping” the computing device 102. Thus, when the computing device 102 is in range, the transfer manager module 112 of the computing device 102 sends one or more of the portions of the content 118 over the lower power wireless communication connection. In one or more implementations, the transfer manager module 114 requests specific portions of the content 118, such as to request the N content portion 204 due to a previous transfer of the first content portion 202.

In another instance, the transfer manager module 112 of the computing device 102 detects availability of the wearable device 104 via the low power wireless communication connection and controls the transfer of the first through N content portions 202, 204. Therefore, the transfer of the portions of the content 118 is controllable by the computing device 102 or the wearable device 104 and thus expands functionality available via the wearable device 104, such as to function as a personal assistant through playback of audio that includes reminders, notifications, and so forth. The transfer may also be performed using a plurality of computing devices, an example of which is described in the following and is shown in a corresponding figure.

FIG. 3 depicts a system 300 in an example implementation in which control of transfer of content over a low power wireless connection is managed using a plurality of computing devices to transfer the content. This system 300 includes the computing device 102 and the wearable device 104 of FIG. 2 as having respective transfer manager modules 112, 114, and the computing device 102 including content 118 having first through N content portions 202, 204.

The system 300 also includes another computing device 302 having a transfer manager module 304 and the content 118 having first through N content portions 202, 204. In this example, the wearable device 104 receives portions of the content that are transferred using different computing devices. A user, for instance, may have access to both computing devices 102, 302, such as associated with a user account maintained by the service backend 106 of FIG. 1. Accordingly, the transfer manager modules 112, 114, 304 are configured in this instance to leverage different availabilities of low power wireless communication connections between the computing devices 102, 302, and the wearable device 104.

The user, for instance, wears the wearable device 104 at a home where computing device 102 is available to transfer the first content portion 202. The user then leaves for work, which causes the transfer to cease. Once at work, computing device 302 is available to complete the transfer of the content 118 through communication of the N content portion 204. As before, this management is controllable by the transfer manager module 114 of the wearable device 104 (e.g., to request particular portions of the content 118), by the transfer manager modules 112, 304 of the computing devices 102, 302, or a combination of the two. Control of the transfer is also performable by the service backend 106, an example of which is described in the following and shown in a corresponding figure.

FIG. 4 depicts a system 400 in an example implementation in which control of transfer of content over a low power wireless connection is managed by a service backend of FIG. 1. This example follows the previous example in which a plurality of computing devices 102, 302 are used to transfer content 118 to the wearable device 104. In this example, however, control of this transfer is managed by a service backend 106.

The service backend 106, for instance, may monitor user login to a user's account through computing device 302, such as part of a social network service, to roam user settings, e.g., user preferences, and so on. As part of this login, the transfer manager module 116 detects that the wearable device 104 is communicatively coupled to the computing device 302. The transfer manager module 116 in this instance continues transfer of the content 118, such as to communicate N content portion 204 to the computing device 302 for communication to the wearable device 104 to supplement a previously communicated first content portion 202 from computing device 102.

Thus, the service backend 106 in this case distributes the first through N content portions 202, 204 to computing devices 102, 302 to cause transfer to the wearable device 104. A pull model is also contemplated in which the wearable device 104 pings the computing device 302 to obtain the N content portion 204 identified in a request formed by the wearable device 104.

As described above, the transfer manager modules 112, 114, 116 are configurable to support a variety of different low energy wireless protocols that save power yet still support transfer of content 118 such as audio and video. This is usable to expand functionality available via small, low-power wearable devices 104, such to function as a personal assistant. Further discussion of these are other examples is described in relation to the following procedure.

Example Procedures

The following discussion describes low-power wireless content communication techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, or software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to FIGS. 1-4.

FIG. 5 depicts a procedure 500 in an example implementation in which transfer is managed of portions of content over a low power wireless communication connection. A transfer of content to the wearable device is initiated over the lower power wireless communication connection to support playback of the content at the wearable device, in which the low power wireless communication connection does not support streaming of the content in an amount sufficient to support real time playback of the content at the wearable device (block 502). As previously described, the transfer may be initiated by the computing device 102, the wearable device 104, and even a service backend 106.

The transfer is managed of a plurality of portions of the content to the wearable device over the lower power wireless communication connection in which individual ones of the plurality of portions are transferred from the one or more computing device responsive to availability of the lower power wireless communication connection with the one or more computing devices (block 504). This availability may be based on whether the wearable device 104 is within range of the low power wireless communication connection with the computing device 102, which devices are available to perform the transfer as shown in FIG. 3, and so forth.

The plurality of portions of the content are caused to be stored locally at the wearable device (block 506). The transfer manager modules 112, 114, 116, for instance, are configured to cause transfer of first through N content portions 202, 204 of the content 118 such that the wearable device 104 is configured to store the content 118 locally on the device, e.g., in memory. Playback is performed of the plurality of portions of the content from the storage (block 508). Playback, for instance, may be configured by the content to occur responsive to an event (e.g., a reminder), when initiated by a user (e.g., playback of a desired song), and so forth.
